Lately I have been hearing a strange very emberassing noise coming from the exhaust (atleast that's where i think its coming from. It doesn't occur in idle, nor does it occur at constant speed (except at a constant speed up a hill). It basically only occurs when i tap on the gas when driving or when I drive up a hill (it's loudest then). It's difficult to describe but it sounds like something is rolling around in the tailpipe or somewhere underneath the car. I climbed underneath the other day to see if anything was loose but there was nothing, the only thing that i noticed is the exhaust tip was badly rusted off and flaking. I will probably take it to a local shop sometime soon, but was wondering if anybody has any ideas what it could be. Could that exhaust tip make all that noise?
